Bzr：由於UTF-8錯誤，無法導入Mercurial（Hg）存儲庫

Question

我有一個Mercurial存儲庫，可成功導出爲「快速導入」格式。但是，當我嘗試導入時，它會因'utf8'錯誤而失敗：

...

16:03:52 900/2100 commits processed at 157/minute (900) 
ABORT: exception occurred processing commit :901

    return codecs.utf_8_decode(input, errors, True) 
UnicodeDecodeError: 'utf8' codec can't decode byte 0xb9 in position 14: unexpected code byte 

我在Ubuntu上運行此操作。 bzr版本「2.4.0-1〜bazaar1〜lucid1」和bzr-fastimport版本「0.11.0-1〜lucid1」。

成功轉換此存儲庫的任何想法？

發生此錯誤是因爲輸入流中有無效的數據utf8; Mercurial通常只存儲utf8數據，但較舊的提交可能仍包含utf8無效數據（請參閱https://www.mercurial-scm.org/wiki/EncodingStrategy）。

請針對bzr-fastimport（https://launchpad.net/bzr-fastimport）提交有關此問題的錯誤。它應該更優雅地處理這種情況;大概它會警告你，有utf8無效數據，然後替換utf8無效字符。

作爲一個權宜之計，您可以在/usr/lib/pymodules/python2.6/bzrlib上將path.decode（'utf-8'）更改爲path.decode（'utf-8'，'replace'） /plugins/fastimport/bzr_commit_handler.py第890行。
